All I did was buy a nice pair of D's on Ebay. They look and feel real and came with a bra too. If you go with a full chest piece it can be as high as 800 but I got these for 90. I have never been happier. mind you I am a MtF transgender and need them anyhow until real ones eventually grow, if they do. HRT doesn't always grow them. I have the D's in this new picture I took today. they were the exact size i needed for my frame. Try t stay clear of the big jugs as they just look silly.
